Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Key Facts about NPT

•Nepal Time is UTC+05:45 — a 45-minute offset, not a whole or half hour.
•The 45-minute offset was adopted in 1986 to match Kathmandu's solar time.
•Nepal does not observe daylight saving time.
•Nepal is 15 minutes ahead of India, despite sharing a long open border.

Understanding the -8h 45m Gap: NPT vs BRT

NPT runs on Nepal Time (NPT) at UTC+05:45. BRT runs on Brasilia Time (BRT) at UTC-03:00. That puts NPT 8 hours 45 minutes behind BRT — a difference of -8h 45m at the current offsets.

In practice, when it is 9:00 AM in NPT it is 12:15 AM in BRT. Midnight in NPT is 3:15 PM in BRT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NPT to BRT time

Scheduling a call from NPT to BRT: a 10:00 AM start in NPT lands at 1:15 AM in BRT, so you can confirm the slot without doing the arithmetic yourself.
Handling a -8h 45m gap: NPT and BRT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in BRT is 12:15 AM in NPT.
Coordinating a NPT-based team with BRT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a -8h 45m gap is not.
With a -8h 45m gap there is no shared 9-to-5 window, so alternate the early start: one week NPT takes the early slot, the next week BRT does.

About NPT (Nepal Time)

Nepal Time (NPT) runs at UTC+05:45, one of only a handful of time zones worldwide that are not a whole or half hour from UTC. Nepal set its offset to 5 hours 45 minutes ahead of UTC in 1986 to mark the country's position between the 75°E and 90°E meridians; Kathmandu's solar time sits just over 5 hours 41 minutes ahead of Greenwich, so the 45-minute offset tracks the sun more closely than either 5:30 or 6:00 would. Nepal does not observe daylight saving time, so NPT is fixed all year. The offset makes Nepal 15 minutes ahead of India Standard Time (UTC+05:30) and 2 hours 15 minutes ahead of Dubai (UTC+04:00).

About BRT (Brasilia Time)

Brasilia Time (BRT) is the standard time in the most populous regions of Brazil, including São Paulo, Rio de Janeiro, and the capital Brasília. Brazil abolished daylight saving time in 2019, so BRT is now observed year-round in these regions. Brazil spans four time zones in total.

Best time to call between NPT and BRT

With a -8h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. BRT opens at 9:00 AM BRT, which is 12:15 AM in NPT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

NPT and BRT have no shared working hours because of the -8h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.

NPT is 8 hours 45 minutes behind BRT (NPT UTC+05:45 → BRT UTC-03:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
